Appellants were found guilty by the court below, sitting without a jury, of facilitation of the transportation and concealment of heroin in violation of 21 U.S. C.A. § 174, and the purchase of the same heroin not in or from the original stamped package, in violation of 26 U.S.C.A. § 4704.

The sole contention of appellants is that the court erred in denying their motion to suppress as evidence the heroin and certain other property seized during what appellants claim was an illegal search. We pretermit a discussion of whether, considering the relevant facts and circumstances, there was a border search (19 U.S.C.A. §§ 482, 1581, 1582); *521 for we agree with the trial court that Galanos, the arresting officer, had before him facts and circumstances within his knowledge sufficient in themselves to warrant a man of reasonable caution in the belief that an offense had been or was being committed; and thus there was probable cause.

Affirmed.
